This paper describes about a method of clothing classification using a single image. The method assumes to be used for building autonomous systems, with the purpose of recognizing day-to-day clothing thrown casually. A set of Gabor filters is applied to an input image, and then several image features that are invariant to translation, rotation and scale are(More)
This paper describes an image based clothes detection method. Our method enables daily assistive robots to find clothes which are readily placed on real environments. No prior knowledge related to shape model or color information is needed because wrinkles on a cloth are extracted as image feature. The feature is constructed through SVM learning by using(More)
|Many countries around the world face three major issues associated with their aging societies: a declining population, an increasing proportion of seniors, and an increasing number of single-person households. To explore assistive technologies that can help solve the problems faced by aging societies, we have tested several information and robot(More)
This paper describes a software system integration of daily assistive robots. Several tasks related to cleaning and tidying up rooms are focused on. Recognition and motion generation functions needed to perform daily assistance are developed, and these functions are used to design various behaviors involved in daily assistance. In our approach, the robot(More)
This paper describes a novel framework for object picking and carrying task by a mobile manipulator. Conventionally, researches on mobile manipulator cope well with object manipulation task with utilizing predefined knowledge or specific tools. So these researches have an essential problem that a new target object cannot be added without relatively many(More)
This paper describes a demonstrative research of daily assistive robots. Several tasks related to cleaning and tidying up rooms are focused on, a real robot performs these tasks. A software system combining environment recognition with motion generation provides functions of finding failures and planning retry behaviors, the robot can do the given tasks(More)
This paper describes about a method of state observation of clothes. The method assumes to be applied as a visual function of daily assistive robots tidying up clothes in daily environment. A set of gabor filters are applied to an input image by changing its frequency and direction. Combination and selection of these parameters provide adequate information(More)
This paper describes 3-D shape modeling performed by a mobile robot. We propose a method in which the robot in the real environment acquires the accurate shape and constructs a 3-D model of an object using Computer Vision techniques under the condition that position and shape of the object is unknown. 3-D modeling is performed from image streams which are(More)
This paper describes a grasp planning for a mobile manipulator which works in real environment. Mobile robot studies up to now that manipulate an object in real world practically use ID tag on an object or an object model which is given to the robot in advance. The authors aim to develop a mobile manipulator that can acquire an object model through video(More)
